从扩展的Gibrat定律推导分布
Derivation of the distribution from extended Gibrat's law
摘要:
利用2002年和2003年日本企业的利润数据,我们发现在中等利润区域,非吉布拉特定律成立。根据各区域的细致平衡定律、高区域的Gibrat定律和中间区域的非Gibrat定律,从运动学角度统一推导出了高、中间区域的利润分配函数。分布函数与经验数据精确拟合,无需任何拟合参数。
英文摘要:
Employing profits data of Japanese companies in 2002 and 2003, we identify the non-Gibrat's law which holds in the middle profits region. From the law of detailed balance in all regions, Gibrat's law in the high region and the non-Gibrat's law in the middle region, we kinematically derive the profits distribution function in the high and middle range uniformly. The distribution function accurately fits with empirical data without any fitting parameter.
